feat(mpc-system): 添加 debug 命令用于故障排查
新增 debug 命令，显示以下信息： - 环境变量配置状态 - PostgreSQL 连接测试（使用 mpc.env 中的密码） - Redis 连接测试 - RabbitMQ 状态检查 - 端口监听状态（5432, 6379, 5672, 50051, 50052, 8080） - 各服务最近 10 条日志 - 手动测试命令提示 使用方法： sudo ./scripts/deploy.sh debug 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
